ABSTRACT
Transposition of the great arteries (TGA) is a cyanotic congenital heart disease characterized by ventriculoarterial discordance and atrioventricular concordance with the great arteries in a parallel relationship. Prenatal diagnosis of TGA has implications for postnatal outcomes, allowing for planned delivery and perinatal management. Three-dimensional virtual or physical models of fetal TGA allow better understanding of fetal cardiac anomalies by parents and interactive discussion among the multidisciplinary team (obstetricians, pediatricians, maternal-fetal specialists, pediatric cardiologists, and cardiovascular surgeons), as well as continuing medical education.

Three-dimensional reconstructions provide a spatial view of the congenital heart disease with a better understanding of the pathology for parents and allow interactive discussion among the medical team (maternal-fetal medicine specialist, neonatology, pediatric cardiology, and cardiovascular surgeon) and improve both objective knowledge and learner satisfaction for medical students.

3D virtual and physical models from ultrasound scan data allow a 3D spatial view of congenital heart anomalies, interactive discussion among a multidisciplinary team, and improved parental counseling. To the best of our knowledge, this is the first description of 3D physical and virtual models of a fetal Ebstein anomaly.

Congenital diverticulum is a very rare congenital heart disease. 3D virtual and physical models from ultrasound scan data provide a spatial visualization and better understanding of congenital heart disease to the parents and support possible surgical procedures.

The purpose of this article is to describe the evaluation of a variety of congenital heart diseases (CHDs) using three-dimensional (3D) ultrasound with different software, such as Cristal Vue, Realistic Vue, LumiFlow, and Spatiotemporal Image Correlation (STIC), with HDlive and HDlive Flow Silhouette modes. These technologies provide realistic images of the fetal heart and cardiac vessels using a fixed virtual light source that allows the operator to freely select a better light source position to enhance the cardiovascular anatomical details. In addition, Fetal Intelligent Navigation Echocardiography (FINE) technology, also known as "5D Heart" or "5D", is a technology that enables the automatic reconstruction of the nine standard fetal echocardiographic views and can alert non-specialists to suspected CHD. Through the use of artificial intelligence, an ultrasound machine is able to perform automatic anatomical and functional measurements. In addition, hese technologies enable the reconstruction of fetal cardiac structures in realistic images, improving the depth perception and resolution of anatomic cardiac details and blood vessels compared to those of standard two-dimensional (2D) ultrasound.
